Troy Johnston Bio
Troy Michael Johnston is an American professional baseball first baseman and outfielder for the Colorado Rockies of Major League Baseball (MLB). He made his Major League debut in 2025 with the Miami Marlins before joining the Rockies organization later that same year. A left-handed hitting corner bat with outfield experience, Johnston has worked his way through the Marlins minor league system since being drafted in 2019.
Born and raised in the Pacific Northwest, Johnston developed into a steady run producer in college and built on that foundation in the lower minors. By the time he reached Triple-A Jacksonville, he was drawing attention as a disciplined hitter with a knack for putting the ball in play and reaching base.
Early Life and Background
Troy Michael Johnston was born on June 22, 1997, in Puyallup, Washington. He grew up in the Puget Sound region, an area with a strong high school baseball culture, and attended Governor John R. Rogers High School in Puyallup. As a young player in Washington, he developed the contact-oriented hitting approach that has remained a hallmark of his game.
After high school, Johnston continued his baseball career at Gonzaga University, where he played college baseball for the Bulldogs. The Gonzaga program gave him the opportunity to face high-level college competition on the West Coast and helped position him for the next step in his development as a professional prospect.
Path to Baseball
Johnston’s path to professional baseball began in earnest when he was selected by the Miami Marlins in the 17th round, 501st overall, of the 2019 Major League Baseball draft. He made his professional debut that summer with the Batavia Muckdogs, getting his first taste of full-season minor league baseball as a position player in the Marlins farm system.
Like many players in his draft class, Johnston saw his development interrupted in 2020 when the minor league season was canceled because of the COVID-19 pandemic. He returned to play in 2021, spending time with the Jupiter Hammerheads and the Beloit Snappers, and later that offseason gained valuable reps by playing in the Arizona Fall League against top prospects from other organizations.
Troy Johnston Career
Early Career (2019–2024)
Johnston opened his professional career with Batavia in 2019 before the pandemic pause slowed his progress. After returning in 2021, he split the year between Jupiter and Beloit, showing the kind of plate discipline that the Marlins look for in their position-player pipeline. His Arizona Fall League assignment at the end of that season offered a clearer view of how the organization viewed his long-term potential.
In 2022, Johnston began the year with the Double-A Pensacola Blue Wahoos, taking another step up the Marlins ladder. He continued to progress through the upper levels of the minor leagues over the following seasons, refining his approach as a first baseman while adding occasional outfield work to broaden his defensive profile.
Miami Marlins Breakthrough (2025)
Johnston opened the 2025 season with the Triple-A Jacksonville Jumbo Shrimp, where he served as one of the Marlins’ top power-and-on-base threats in the upper minors. Over his first 84 games of the year, he hit .252 with a .333 on-base percentage and a .439 slugging percentage, slugging 12 home runs, driving in 39 runs, and swiping 31 bases, a combination of pop and speed that pointed to a well-rounded offensive profile.
On July 29, 2025, the Marlins selected Johnston to the 40-man roster and promoted him to the major leagues for the first time, making his MLB debut that day. Less than three weeks later, on August 16, 2025, he hit his first career home run, taking Boston Red Sox pitcher Brayan Bello deep. The home run marked a clear milestone in his transition from a prospect to a contributing big leaguer.
Colorado Rockies Era (2025–Present)
On November 5, 2025, the Colorado Rockies claimed Troy Johnston off waivers, ending his brief tenure on the Marlins’ major league roster. The move gave the Rockies a young corner bat with Minor League track record of on-base skills and extra-base pop, and it gave Johnston an opportunity to compete for a regular role in a new organization.
Wearing uniform No. 20 for the Rockies, Johnston slotted into a depth chart that included first base and corner outfield. Through the early portion of the 2026 season, he has been a productive presence in the lineup, posting a .304 batting average with 7 home runs and 47 runs batted in, numbers that reflect his track record as a run producer in the minors and signal an emerging everyday contributor at the highest level.
Notable Events and Milestones
Johnston’s first Major League home run off Brayan Bello of the Boston Red Sox on August 16, 2025, stands as the signature early moment of his big-league career. Being claimed by the Colorado Rockies just a few months later added a quick offseason chapter to his story, and his production through the early part of the 2026 schedule has built further momentum.

Troy Johnston’s Major League career is still in its early chapters, but he has already produced several milestones. His MLB debut came on July 29, 2025, with the Miami Marlins, and he wasted little time delivering a signature moment, going deep for his first career home run on August 16, 2025, against the Boston Red Sox. After being claimed by the Colorado Rockies, he continued to add to that ledger in 2026.

Personal Life
Troy Michael Johnston was raised in Puyallup, Washington, where he attended Governor John R. Rogers High School before going on to play college baseball at Gonzaga University. He keeps much of his personal and family life out of the public eye, and few additional personal details have been confirmed beyond his Pacific Northwest roots and his path through the Marlins and Rockies organizations.
2025 Season Performance
Troy Johnston’s 2025 season was defined by a breakthrough at the highest level. He began the year dominating at Triple-A Jacksonville, hitting .252/.333/.439 with 12 home runs, 39 RBI, and 31 stolen bases over his first 84 games, numbers that made him one of the most talked-about bats in the Marlins system and forced the front office’s hand at the trade deadline window.
His July 29 promotion to the Marlins and his first Major League home run on August 16 against the Boston Red Sox gave him a rapid introduction to big-league pitching. The strong finish in Miami carried over into the offseason, when the Colorado Rockies claimed him off waivers on November 5, 2025, setting the stage for an expanded role in 2026.
Looking ahead, Johnston’s early 2026 production with the Rockies, a .304 batting average, 7 home runs, and 47 RBI through the early going, suggests a player who has turned a brief 2025 cameo into a sustainable spot in a Major League lineup. With his combination of contact, power, and speed, his outlook in Colorado points toward an everyday role as the season progresses.
